Garmin builds a smartphone head-up display for a tenth the cost of what automakers charge. Displayed information includes turn arrows, distance to the next turn, your speed, the speed limit, excessive speed, estimated time of arrival, and lane guidance (which lane for exits vs. through traffic). If you subscribe to premium services, you can also get traffic info and photo radar alerts.

Today a rather cryptic release from 5D Robotics hinted at a growing trend in military research: rather than finding new and innovative ways to strap weight to our human soldiers, how about we just bring along a robot pack mule or two?

At the next nebula, take a right. Here’s a good one for you: When we eventually launch a spacecraft that’s capable of exploring the Milky Way, how will we navigate between the stars? According to some German researchers at the Max Planck Institute, we’ll use intergalactic pulsar-based GPS.

No matter how good satellite navigation systems get, they still don’t work where we spend the majority of our time: indoors. A company called ByteLight is trying to change this situation with a system that uses LED lighting to provide devices with accurate location data.

When the American Civil Liberties Union (ACLU) filed a Freedom of Information Act request for an explanation of how the FBI plans to use GPS tracking, the government responded by releasing two heavily redacted memos. Actual information on how the FBI and Justice Department interpret their latitude regarding the ruling isn’t being released.
